makes many people probably not expect that there are many "lakes" in Taklamakan Desert in my country. This rare situation is indeed a "great contrast" in 2022.
So, after seeing this scene, many people wonder whether the northwest of our country really wants to become "Jiangnan"? The rainfall in the Yangtze River is extremely low.
Indeed, such climate change is really "a handful of snot and tears", and it is impossible not to be sad. So what's going on? Let’s take a look step by step, is it that China’s rainfall belt has really moved northward? Is this the trend in the future?
is rare! There are many lakes in the Taklamakan Desert
Taklamakan Desert is located in the center of the Tarim Basin in southern Xinjiang, my country, and is the largest desert in my country and the tenth largest desert in the world.
Of course, since it is called a desert, it must be mainly based on "less rain". Indeed, the average annual precipitation in this desert area does not exceed 100 mm, and the minimum is only four or five mm, while the average evaporation is as high as 2500-3400 mm.
So, even if there is water, it is basically completely "evaporated". But seeing many lakes appear in the Taklamakan Desert is bound to be a rare thing.
That’s right, the low rainfall in the Yangtze River Basin in my country this year is obvious, but for this dry desert area of my country, it has unexpectedly increased.
According to CCTV, this year is the Tarim River in Xinjiang - the year with the largest water volume in the past 10 years. With the continuous influx of rain, the river overflows into the nearby Taklamakan Desert, forming many lakes, and the scene is spectacular.
It is indeed clear from the picture that the lakes in the desert are not small, so they form a unique landscape.
Of course, many people will say that this is a good thing when they see this, and the desert turns into an "oasis" is just around the corner. Indeed, in this regard, it is a good thing. For the areas around the desert, as long as they become "greener", the impact of sand and dust will be much smaller.
However, in general, the overall rainwater has caused many people to discuss the changes in rainwater.
China's rainfall belt moves northward, and the northwest becomes Jiangnan?
This is also a coincidence. We just talked about climate change in the northwest, and the news came about that many "lakes" appeared in the Taklamakan Desert.
Indeed, under Global Warming , my country has been greatly affected by changes in rainfall. After all, my country is one of the sensitive areas of global warming, and the degree of warming is still increasing.
According to the data of the "China Climate Change Blue Book (2022)", in 2021, global warming continued to develop, and once again showed that it was 1.11℃ higher than the pre-industrial level (average from 1850 to 1900).
For my country, it also set a record high. The annual average surface temperature in China showed a significant upward trend, with a temperature increase of 0.26℃/10 years, higher than the global average heating level during the same period (0.15℃/10 years).
The past 20 years are the warmest period in China since the beginning of the 20th century. In 2021, the average surface temperature in China was 0.97℃ higher than the usual value, the highest since 1901. Therefore, our country is warming as a whole, so the northwest region is one of the warming areas.
Yes, warming in northwest my country is also happening, and rainfall is also showing an upward trend.
According to the warming and wet data released by my country, the average annual temperature increase rate in the northwest region was 0.30℃/10 years, while the national temperature was 0.23℃/10 years and the global temperature was 0.12℃/10 years.
At the same time, rainfall is also showing an increase overall trend. The annual precipitation increase rate in Xinjiang is 9.6 mm/10 years, and 5.4 mm/10 years in central and western Gansu.
So, the northwest region has indeed increased rainfall.
And for 2022, under the huge climate change, the climate change in the northwest region may actually be greater. Why?
Many people should have noticed that this year, the subtropical high pressure in the northwest Pacific region of is very strong, and it is always "rushing" to Qinghai-Tibet Plateau , so it is inevitable that the "hot" state may be increased.
is also easy to transport warm currents, so the northwest region of my country itself is an active "hole" of "cold air".
Therefore, the development of cold and heating air flow is indeed easy to cause rainwater. Therefore, from this perspective, the increase in rainfall in the northwest can still be explained.
Of course, there is also the monsoon change - the impact of the monsoon rain formed also exists. Therefore, there are many factors in climate change in the northwest, not single.
Does this mean that China's rainfall belt moves northward and the northwest will change to Jiangnan? If we don’t look at these situations, the facts have proved that the northward migration trend of rainfall belts in our country is emerging.
In recent years, rainfall in northern my country has increased significantly, and there is no way to deny this.
For example: In 2021, the precipitation in the north was the second most in history, second only to 1964, and the annual precipitation in Beijing, Tianjin and Hebei was the most in history.
Moreover, in 2015, the Chinese Science team clearly issued a statement in the journal Journal of the National Academy of Sciences, that is, global warming will cause the northward movement of the summer monsoon zone of East Asia, thus bringing rich precipitation to northern China.
At the same time, from the geological records, global warming will definitely push the East Asian summer monsoon and rain belt to the northwest, thereby greatly improving the ecological environment in northern my country.
So, has China's rainfall belt moved northward? It was indeed moved north. Then the northwest really will become Jiangnan?
In fact, this is how it develops from the perspective of trends. However, it is unlikely that the northwest will really become Jiangnan. After all, this rainwater development trend exists, but its reality has not changed much to the overall climate in the northwest.
So, compared with the desert areas in the northwest, this impact may be just the "tip of the iceberg", unless such a situation continues to develop, then this possibility is there. However, if such changes really occur, climate change in other regions of our country may also occur.
So, in fact, the rainfall belt moves northward, causing the increase in rainfall in the northwest region, which may not be all good.
can only be said that the development of this climate model is really too complicated. In the future, will more unusual climate changes occur in the northwest under the climate change of global warming? I can only observe.
Summary
Overall, as a global climate-sensitive region, my country is indeed a bit "not friendly" in such a climate change. It can also be seen from the climate change in 2022 that the climate change in my country is extremely changing. If this continues, it also means that there will be more huge changes in the future climate. Therefore, there is not much time left for humans to change the climate.
Although we are talking about our country's climate here, other countries don't have to be happy. The global climate changes in 2022, and many countries are affected. Many people should have seen that Europe, Africa, America and other places have encountered extreme high temperatures and low rainy climates. Therefore, climate change is a global impact, not just our country.
